Application filed December 9, 1927. Serial No. 238,762.

This invention relates to resilient or spring padding structures. r

Resilient or spring pressed pads have many uses, onesuch use being inironing machines. 5 In such machines the ironing elements, as forinstance the ironing rolls,have their outer ironing surfaces providedwith resilient pads to permit the surface to give or be depressed bybuttons, hooks, orother project-ions carried by the garments passingthrough the machine Thel invention has for its salient object to providea resilientpad structure that is sirnplein construction and that can beeasily and quickly applied to the ironing element of an ironing machineor to any other structure at a minimum of expense.

Another object of the invention is to prol vide/a resilient padstructure so constructed and arranged that the springs or resilientelements are firmly and securely held in position under tension. f

Further objects of the invention will'appear from the followingspecification taken in connection withthe drawings, which form a part ofthis application, and in which Fig. 1 is a plan view partly broken awayof an ironing roll having a resilient pad structure constructed inyaccordance with the invention; l

i. The invention briefly describedconsists/ofl 'aresilient'pad structurein which the ele,-

* .menttowliich the padis to be secured is providfedlwith a groove ,orgroovesv and a pluralit .of springs are secured toithe outer surface :0theelement bysrecuriiig means, such as links, disposed in the groove orgrooves.4 The.

springs are covered by s itable sheeting or a covering 'of felt or othersuitable material.

In theJ particular embodiments of the inven tion illustrated theresilient pad structure has been,shoWn in connection -with theironingelements of an ironing machine'y but it should be understood thatthe structure is not limited to this particular use and may be used inmany other ways. For instance, the springs used in' upholsteringfurniture could be secured in the manner/illustrated and hereinafter,described.

Further details ofq the invention will appear fr om the followingdescription.

In Fig. L there is shown an ironing roll 10 )for use i an ironingmachine. The roll consists of a metallic shell 11, the outer surface 0fwhich,las shown in Figs. 1 and 2, is pro-l vided with a spiral groove15.l This groove extends spirallyaround the outer surface of the rollfrom' one end to the other thereof. -In the. form of the inventionillustrated in Figs. 1 to 4. inclusive, a plurality 'of setsI of springsA, B, G,`D., etc. are secured to the outer surface of the roll'10. Eachset comprises a pair of springs 1 6 and 17, prefer- Vably of the spiraltype, the two springs 16 and 17 being integrally connected by a portion18. These sets of springs may be formed by straightening out oneconvolution of the.

spring and bending the springs intovparallel Y' relation as shown in Fi2.

rllhe-'end spring16o the lset A is secured p I' Iin position b means `ofa mfe'mber 20 having one .end 21v ooped around the base of the spring 16and `having its .other-,end bent laterally as\shown'at 22 in Fig. 2 andsecured in an aperture 23 formed'in the shell 11 in any suitable manner,as by means of a vscrew 24.

is disposed in the groove 15.

`Itwill'be noted that the securing member 20 The sets of springs are'connected/tbgether by means of links 25, theF ends -ofthe links beinglooped around the bases of the springs of successive .sets andthe links,as shown in Figs. 2'and 3, being disposed' in the groove 15.

After the sets of springs are connected by means of the links 25thesring structure is wound around the roll an the links 25 are seated inthe groove. The spring at the other end of the spring structure is thenconnected to the shell by means of a member similar to the securingmember 2Q.

The spring structure can be stretched tightly around the roll as it isWound thereon, thus securing the springs firmly and securely to theouter surface of the shell under tension.

After the springs have been secured in the manner above described or inthe manner hereinafter set forth, a suitable covering of sheeting, feltor other suitable material is Wound tightly around the outer ends of thesprings.

In the form ofthe invention shown in Fig.

f 5, the springs are not secured in sets of two each but each spring 36is secured to the adjacent springs by means of links 37 which aredisposed in the groove in the same manner as the links 25 in the form ofthe invention already described.

In Fig. 6 a different type of ironing element is illustrated. |Theironing 'element in this case consists of a pressing shoe or board usedparticularly for pressing clothes. The board 45 is groov'ed, as shown at4G, and springs 47 are secured to the board over the grooves in themanner shown in Figs. l to 4 or in Fig. 5. At one end of each set ofsprings there is provided an eye bolt 50 having one end 5l threaded andprovided with a nut 52. rIhe eye bolt is connected to the end spring andextends through a flange 53 at the end of the board or shoe. By turningthe nut the set of springs can be placed un der tension and securelyheld in position. The springs are covered by a suitable cover-` ing 48as in the other embodiment of the in` vention.

From the foregoing description it will be seen that a simple, practicaland inexpensiveY spring pad structure has been vdesigned and that springpadding can be'easily, quickly and economically secured to anydesiredsurface in the manner described. Furthermore, it Will be clearthat the springs Will be firmly and securely held in place.

l Although certain specific embodiments of the invention have beenparticularly shoWn` and described, itWill be understood that theinvention is capable of modificationand that changes in the constructionand in the arrangement of the various cooperating parts may be madeWithout departing from the spirit or vscope of the invention, asexpressed in the yfollowing claims.

What I claim is: l

1. A resilient pad structurefcomprising a member having grooves therein,a plurality .of springs, and linksv connecting and securing said springsand disposed in said grooves.

my hand this 7th day 2. A resilient pad structure comprising a memberhaving a groove therein, a plurality of springs disposed over saidgroove and seated against the surface of the member, and meansconnecting said springs anddisposed in said groove.

' A resilient pad `structure comprising a member having groove therein,a plurality of sliirings disposed over said groove `and seated againstthe surface of the member, means connectingssaid springs and disposed insaid groove, and anchoring means for seagainst the surface of saidelement, and

means in said groove for securing the springs to the element. p

7. In combination, a member having a groove therein, a resilient padstructure securedvto said member and comprising a plurality of sets ofsprings, each set comprising a pair of springs having their basesconnected together, and means in said groove secured to and connectingsaid sets of springs.

8. In combination, a member having a groove therein, a resilient padstructure secured to said member and comprising a plurality of sets ofsprings, each set comprising a pair of springs having their basesconnected together by an` integral connecting member, and means in saidgroove secured to and connecting said sets of springs.

9. In combination, an ironing roll having a circumferential spiralgroove therein, a plurality of springs having their bases seated againstthe surface of said roll, and means in 'said groove for securing thesprings to the roll.

10. An ironing roll comprising a shell having a spiral groove in itsouter surface, ya plurality of springs arranged spirally around saidshell over. said groove, means in said groove securing said springs toeach other, means in said groove securing the end springs to said shell,and a flexible covering surrounding' said springs.
